LD6 entry: Photon

Photon was my entry to LD6. The theme was “Light and darkness”. I still remember all the time I fiddled with shadow calculations. In my game, each light source does exact shadow calculations with all the level geometry – and in order to still have it all run with < 1% CPU, this was quite some work. Now, there’s nothing special about this except, I wanted to do things in the most simple way possible, this being an LD. And I had to admit utter defeat when I later saw bluescrn’s entry. Instead of spending half of the 48 hours on it like me, he went for a dead simple approach – with the only difference that his was not 100% accurate. Which would have made no visual difference in my game whatsoever. In fact his shadow method would have worked a lot better in my game in just about every respect

I still managed to do quite well. Here’s some screenshots from back then:

The title screen.

The goal of the game is to send all the photons coming from the lamp to the prism, but the problem is, you only can see the areas of the map which are lit up by the moving photons.

To control the photons, you can place mirrors – to light up more areas of a level, and once you have found the prism, send them all to it.

Seems the original submission is still up: original zip at original site
